Abstract:
A lighting device including a light source, one or more input devices, and an electronic processor. The electronic processor is configured to receive an input to illuminate the light source at a first illumination intensity value associated with a first operating mode and operate the light source at the first illumination intensity value based on the received input. The electronic processor is further configured to initiate a ramp-down operation of the light source from the first illumination intensity value. The electronic processor is further configured to receive a first mode change input to change from the first operation mode to a second operating mode at a first time, wherein a second illumination intensity value is associated with the second operating mode, and, in response to receiving the first mode change input, control the output of the light source to output a third illumination intensity value.
